If your 2009 Ford F-150 Triton 4.6 liter V8 is having trouble starting when hot, it could be a faulty coolant sensor. In this guide, I’ll show you how to locate and replace the temperature coolant sensor in your Ford F-150.
The temperature coolant sensor is located underneath the alternator. You’ll need to remove the alternator to access the sensor. When the sensor starts to go bad, the engine may have trouble starting when hot as it doesn’t know the correct temperature, leading to either choking or flooding.
To access the sensor, you’ll need a flat blade screwdriver to release the clip holding it in place. It’s important to ensure your safety by disconnecting the battery before starting any work to avoid any accidents. Additionally, using gloves is recommended to prevent touching any live components.
When replacing the sensor, using a swivel, a 19-millimeter socket, and extension will make the job easier. Also, a serpentine belt tool comes in handy to assist with getting the belt back in place after removing the alternator.
After replacing the sensor, ensure it is tightly secured without over-tightening to prevent damaging the plastic. This is crucial to avoid leaks and ensure the proper functioning of the sensor.
Once the replacement is done, reassemble the alternator and ensure everything is securely back in place. Finally, don’t forget to reconnect the battery before testing your newly replaced coolant sensor.
Replacing a faulty coolant sensor can help resolve engine starting issues and improve the overall performance of your Ford F-150 Triton 4.6 liter V8. I hope this guide has been helpful for anyone facing similar problems with their vehicle!
